We're dividing 478316 by 12 
We want to divide 478316 by 12.

Let's proceed to step 1:
When dividing 4 by 12, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 12

Let's proceed to step 2:
When dividing 47 by 12, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 36 away from 47, we end up with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 12

Moving on to step 3:
When dividing 118 by 12, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 108 away from 118, we end up with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 12

Moving on to step 4:
The number 12 fits into 103 8 times, leaving a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 398.0
Deduct 96 from 103 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 12

Advancing to step 5:
71 divided by 12 is 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 3985.0
The remainder is 11 after subtracting 60 from 71.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 12

Step 6:
12 goes into 116 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 39859.0
The remainder is 8 after subtracting 108 from 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 39859.6
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 39859.66
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 39859.66 and a remainder of 0.008.
